Eaton’s FlashGard Motor Control Centers (MCCs) build upon the features and benefits of the Freedom 2100 MCC by adding RotoTrack, a patented state-of-the-art stab racking mechanism that provides bus isolation, stab indication, and lockout features that proactively prevent the initiation of arc flash. They are designed for three-phase, 230V applications up to 300 hp, or three-phase, 480V applications up to 600 hp.
RotoTrack mechanism allows the unit to be disconnected from the vertical bus with the door closed; safest place to be is behind a door while stabbing in a unit.
Optional remote operated racking device can advance and retract the bus stabs from a distance of up to 25 feet, helping maintain the closed-door unit which is instrumental in mitigating an arc event.
Once the stabs are racked out of the vertical bus there is no voltage present in the unit from the bus, providing a safe working environment free of arc flash hazards.
ARC Reduction Maintenance System (ARMS) applied to the breaker feeding the motor control center reduces the trip time during an arc flash.
Unrestrictive racking mechanism prevents over torquing of the RotoTrack.
The Freedom and Freedom FlashGard MCC use as a standard the C306 bi-metal three phase overload, as an option Eaton will provide a C440 Solid Sate Overload (SSOL), a C440 SSOL with integral ground fault or a C441 Advanced SSOL for superior pump and fan control with meter like functions. The overloads can be mixed and matched within an MCC lineup where needed if the application calls for it. Each overload type is capable of being controlled and monitored from DeviceNet, Modbus, Profibus, Modbus TCP and EtherNet/IP.
